Smetana (Ottawa), PTT also in cN, cT and in cP .
Description: About as in S. persubtilis nov.sp.
Length: 2.8-3.4mm (forebody: 1.5-1.6mm).
PM of the HT: HW: 30.8; DE: 16.5; PW: 22.5; PL: 23; EW: 28.5; EL: 24; SL: 19.
Male: Metasternum shallowly impressed, moderately coarsely, densely punctate, interstices smaller than half diameter of punctures. Anterior sternites simple, sternite 7 in posterior middle finer and denser punctate than laterally. Sternite 8 with a very shallow, broad apical emargination (LS: ED= 51:1.5). Sternite 9 with comparatively short, blackish apicolateral teeth. Aedeagus (fig. 40), apical portion of median lobe triangularly narrowed, apex rounded, expulsion hooks connected medially; parameres langer than median lobe, with 9-12 apical setae.
Female: Sternite 8 at posterior margin slightly projecting, rounded apically. Valviver with a short apicolateral tooth. Spermatheca (fig. 70), infundibulum slender, 3x as long as broad.
Median portion of frons strongly elevated, distinctly exceeding beyond the level of medial eye margins; pronotum and elytra with deep impressions, punctation of pronotum strongly, but only shortly, confluent, punctation of pronotum and elytra coarser than in S. persubtilis , diameter of elytral punctures slightly larger than apical cross section of antennal segment 2; abdominal punctation dense, interstices on tergite 7 distinctly smaller than punctures.
Comparative note: This new species has to be identified by examining the sexual characters.
Etymology: Since the identification of this new species is very difficult, I name it " permolestus " (Lat.= very vexatious).
